Thanks, pfft it's just an easy 8-step process

I don't mind that much, there is nothing that can go wrong IMO. With the SGA I ended up gluing the end cap on and in over 50 firings, it's been perfect. The piston in this is so simple, basic and strong that I don't see me having to unscrew the pilot plug in the near future. Before the paint job I did have to replace the sealing face because the washer was a tiny bit too small, only took 10minutes to take the pilot fittings off.

I'm just worried about the paint work most of all, I had to paint the pilot setup black while it was on the cannon, otherwise my plumbing wrench would wreck the paint job.

I'm not sure. These are about 60mm in diameter with a ~15mm diameter hole in the middle.

I have seen bigger ones that are around 100mm+, but they're $12 so I don't bother.

Yeah it does make a great seal, best sealing face i've ever used. I used one on the SGA and my small co-axial.

I clap to you, MrCrowley, for making use of my favorite breech loading system.

Oh yeah, I forgot about the Omega project. Maybe subconsciously my mind was telling me how great a cannon it would've been and to put some features into my new cannon.

It's a great system, can't believe more don't try it. Simple, basic, quick loading, cheap...Only thing is at 90psi the recoil knocks the golfball barrel out of the coupler because it can only fit about 2cm in. So i'll just sand the coupler down a bit and it should be fine.
